Found a macbook on the cheap. It boots and works via external monitor but the screen has no backlight. I've tried a couple inverters that I know to be good. When I first tried to change out the inverter it showed light for about a second then went blank. Now nothing at all. What should I look into yet?
View 2 RepliesTo begin with, I own a MBP Intel Core Duo 2.0/2 Gigs of ram. I've had this laptop for roughly 18 months and do not have Applecare. I take extreme good care of all my stuff and still baby it till this day. I have NEVER bumped the laptop against anything, accidently dropped it too hard on the desk or anything similar along the lines. Essentially, looking new. About 2 days ago, I was working with my laptop and I closed the lid which made the computer go to sleep. Everything all normal & no appearance of anything! Around mid-night, I opened the MBP's lid to check my email. (Computer awakes, I can hear the Superdrive awake) then boom, a blank screen. The monitor did not turn on then burn out, it was always off. Similar to if you dim your monitor all the way. I can still see the desktop however, there is no light. If I take my flashlight and point it to the desktop, I can see everything. I called a few places, and they described it is the Inverter board or could be the fluorescent bulb that is damaged. My reasoning for the inverter board is faulty is because when a fluorescent bulb goes out it, it tends to flicker at first. Researching this forum, I noticed most MBP users LCD's that go out, they flicker but, mine just went out and I can still see the desktop. Where can I order the inverter board? I tried [URL] but they're out of stock. I will change the inverter board myself because it will be quicker and I need to use my laptop. It is currently hooked up to an external monitor until I can get this fixed.

Looking at a PowerBook that has Applecare - The screen in the listing picture is not too bright. The seller has stated that all is well with the screen, but you never know. I am prepared to go for it if the Applecare covers the screen lighting. Applecare cover on notebooks appears to be worldwide - If the screen lighting conks out overseas, I can get it fixed at the local Apple Store?

I logged into my macbook pro the other day and I noticed that my picture was blank (by blank I mean that silhouette icon that you have with new accounts). So i opened my addressbook and reset my picture. A few minutes later, I noticed that my profile picture was reset to blank again so I changed it again and waited. Right before my eyes, the picture changed back to the silhouette again.

View 8 Replies View RelatedI recently took apart my macbook to see if I could get my wifi antenna nudged to work better. It does seem to be fixed, but when I put the laptop back together the inverter cable shorted to the frame, smelled like burning electronics and stopped working. However, I put a new inverter in and it is not fixed. I was careful to note that the second inverter did not create any smell, but the screen did not even light up for a second. The LCD IS still working, as I can see everything on the screen if I shine a light on it. Except for no backlight, the computer works fine. What could possibly be wrong, and what are my options?

Searched the forum, some useful information. Found the following : On amazon Hypershop's car charger I'd like some flexibility, so the Hypershop one is out of the question (being able to charge my android phone separately from laptop, my backup pc laptop, etc). So my question is, what inverter are you using? I found some on best buy (Cyberpower), but there's no wattage listed in their specs.

View 6 Replies View RelatedI have a 15'' 2010 macbook pro that I've only owned for about a month and a half. At first the isight camera worked great,I used it multiple times for photobooth. But a few weeks ago I tried to used it for skype and noticed it just showed a black screen. I thought maybe the problem was just with skype, but I started checking other programs and it's the same in all of them. The green light is on and it's recognized in system profiler, but the screen is black.
A few days after this happened, the problem seemed to fix itself, but then it went right back to the black screen 2 days later, and had been that way ever since.
I tried resetting the PRAM, but it didn't help. Is there anything else I can do, or is it time to give in and take my macbook to the Apple store?
When it did show the screen saver the mouse arrow was on the tv and not on the computer and there were no icons to be found on the tv to click on. Right clicking would only bring up the screen for setting the background pictures.

View 1 Replies View RelatedI got a cheap 1.42ghz 512mb RAM, 14" screen G4 ibook because it had a broken hinge. I tore apart the laptop and replaced the hinge (screen frame) and put it back together. The screen wouldn't work. I opened it back up and found that the video connector was lose, so I connected it and put it back together. BAM!! Everything worked... everything except the sleep feature when the lid is closed. So I opened it back up, took the magnet from the old frame and put it on the new frame (which was missing its magnet).
When I turned it back on the screen was blank/dark. It showed all the signs of classic inverter board burnout (dark screen, can be seen with flashlight from behind, can be seen on external monitor), so I ordered an inverter board and when it arrived, I swapped it out. Still nothing. The next idea would be the backlight, but that doesn't make sense... I'm trying to figure out what might have happened to make the inverter/backlight go from working fine to not working when all I did was removed the screen back case, screw on the magnet and close it up. I have done a bunch of digging around under the hood and am wondering if anyone knows of a possible ground wire, other connection, easily broken wire, or other issue that might have happened. I'm thinking that it might be one of the power wires that goes into the inverter. It might have broken inside the shield, or maybe I was sold another bad inverter board.
So:
Assumption 1: one or both inverter boards are good.
Are there any connections other than the inverter data/power cable from the mobo and the cable from the inverter to the backlight?
Does anything else (backlight, etc) have to be grounded? Where are these groundings?
Would anything else give the same symptoms except the inverter?
How can I test the backlight? I heard that there are two lights in these machines, so if it was one of the florescent lights, only 1/2 the screen would be dark.
Assumption 2: Neither board is good and that is the problem.
How can I test the inverter board (short of an osilascope) to see if it's working?
Is this a good assumption?
I'm about stumped right now and haven't found any direct help on forums. I'm hoping someone in the Mac community has run into this or has an idea about what could be going on. I'm really hoping that I missed something like replacing a screw that is also a ground or something along those lines.
i recently noticed that on some websites the font is different from default
idk how it changed or if i did or somehow, but i want to put it back to default

its not only on websites, but on the mac itself

I have a tough one regarding an iMac G5 ALS 17" 2Mhz I am fixing. First I want to point out that I am familiar with the innards of these ancient beasts as I have fixed a couple 1st gen iMac G5 as well as iSights and Duos.
When I plug in the cord in the PSU, the 1st diagnostic LED comes on but when trying to start the computer the second diagnostic LED comes briefly on and then goes off. Nothing else happens, no chimes, nothing. According to Apple KB this is the sign of a faulty PSU. Yet, I have tried replacing the PSU and I get the same result.
Now the weird part is that if I unhook the LCD cable the computer starts normally (it chimes) with the display off. What is most puzzling is that it will start with the inverter hooked up but the LCD display cable off but will not start with the inverter entirely taken off but with the LCD cable on. It seems that it is the LCD itself that prevent the computer from starting. I thought the inverter would draw current but not the LCD itself so it's probably something else.
Anybody had anything similar happen to them? Could it be that the inverter is faly but it only draws when the LCD is hooked? Could it be some kind of short in the LCD or something that make it draw even with the inverter unhooked?
I just signed into my msn on my Macbook today to find all my messenger contacts blocked, and whenever I tried to unblock them it didn't do anything.
Also when I signed on, almost all the contacts I had showed up like new contact requests, where I had the option to add them or ignore the request. When I used my windows PC with Windows Live, everything was normal and no contacts were blocked.
I am using Messenger:mac version 7.0.2 (090123)
as far as I know, that is the most recent version.
I was normally using my Mac, as usual, when it suddenly crashed. The screen froze up and this icon showed up in the middle...A few minute later, it was still there so I had to force restart my mac. But when it started again, the image of a flashing folder with a question mark appeared. I googled a bit what it could mean, and I quickly found it was something about directory corruption. I tried to open the disk utility as advised to check if the disk was damaged, however it said the disk was alright, and it didn't give me the option to repair it. So now I'm stuck in the disk utility, and my only options are:
- Use time machine (I didn't save my data using it so useless)
- Reinstall OS X (Deleting all my content - exactly what I want to avoid)
- Repair the Disk (Which I can't even do)
So my main question is, is there a way I can get back all my files/data before reinstalling OSX? Are there other ways to repair what is broken without resetting my whole comp? Is it even possible that your mac crashes at any moment, making you lose EVERYTHING for no reason?

I recently bought a new Mac Mini with a 24 inch Philips display. When I connected the display and started up the computer, it booted up and showed the grey apple screen, but it never made it past that. On the screen it reads "cannot display this video mode, change computer display input to 1920x1080@60Hz." As you might have realized, I can't get onto the computer to do so because I cannot see what I am doing. This is extremely frustrating because I had my Mini hooked into my friend's tv and it worked perfectly right away and now I can't even get it to connect. Does anybody know any hotkeys/solutions to this problem?

The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.
